 Hugo reads its configuration from `hugo.yaml` in the root of your Hugo site.
 The config file is where you can configure all aspects of your site.
-You can find the config file for this site in `exampleSite/hugo.yaml` as a good starting point.
+Check out the config file for this site [`exampleSite/hugo.yaml`](https://github.com/imfing/hextra/blob/main/exampleSite/hugo.yaml) on GitHub to get a comprehensive idea of available settings and best practices.

 While `favicon.ico` is generally for older browsers, `favicon.svg` is supported by modern ones. The optional `favicon-dark.svg` can be included for a tailored experience in dark mode.
 Feel free to use tools like [favicon.io](https://favicon.io/) or [favycon](https://github.com/ruisaraiva19/favycon) to generate these icons.
+
+### Theme Configuration
+
+Use the `theme` setting to configure the default theme mode and toggle button, allowing visitors to switch between light or dark mode.
+
+```yaml {filename="hugo.yaml"}
+params:
+  theme:
+    # light | dark | system
+    default: system
+    displayToggle: true
+```
+
+Options for `theme.default`:
+
+- `light` - always use light mode
+- `dark` - always use dark mode
+- `system` - sync with the operating system setting (default)
+
+The `theme.displayToggle` parameter allows you to display a toggle button for changing themes.
+When set to `true`, visitors can switch between light or dark mode, overriding the default setting.
+
+### Page Width
+
+The width of the page can be customized by the `params.page.width` parameter in the config file:
+
+```yaml {filename="hugo.yaml"}
+params:
+  page:
+    # full (100%), wide (90rem), normal (1280px)
+    width: wide
+```
+
+There are three available options: `full`, `wide`, and `normal`. By default, the page width is set to `normal`.
+
+Similarly, the width of the navbar and footer can be customized by the `params.navbar.width` and `params.footer.width` parameters.
+
+### Search Index
+
+Full-text search powered by [FlexSearch](https://github.com/nextapps-de/flexsearch) is enabled by default.
+To customize the search index, set the `params.search.flexsearch.index` parameter in the config file:
+
+```yaml {filename="hugo.yaml"}
+params:
+  # Search
+  search:
+    enable: true
+    type: flexsearch
+
+    flexsearch:
+      # index page by: content | summary | heading | title
+      index: content
+```
+
+Options for `flexsearch.index`:
+
+- `content` - full content of the page (default)
+- `summary` - summary of the page, see [Hugo Content Summaries](https://gohugo.io/content-management/summaries/) for more details
+- `heading` - level 1 and level 2 headings
+- `title` - only include the page title
+
+To exclude a page from the search index, set the `excludeSearch: true` in the front matter of the page:
+
+```yaml {filename="content/docs/guide/configuration.md"}
+---
+title: Configuration
+excludeSearch: true
+---
+```
+
+### Google Analytics
+
+To enable Google Analytics, set the `googleAnalytics` parameter in the config file:

+```yaml {filename="hugo.yaml"}

 ## Configure Content Directory
 
 If we need to use a different directory for our content, we can do so by setting the [`contentDir`](https://gohugo.io/getting-started/configuration/#contentdir) parameter in our site configuration file.
+
+## Add Images
+
+To add images, the easiest way is to put the image files in the same directory as the Markdown file.
+For example, add an image file `image.png` alongside the `my-page.md` file:
+
+{{< filetree/container >}}
+  {{< filetree/folder name="content" >}}
+    {{< filetree/folder name="docs" >}}
+        {{< filetree/file name="my-page.md" >}}
+        {{< filetree/file name="image.png" >}}
+    {{< /filetree/folder >}}
+  {{< /filetree/folder >}}
+{{< /filetree/container >}}
+
+Then, we can use the following Markdown syntax to add the image to the content:
+
+```markdown {filename="content/docs/my-page.md"}
+![](image.png)
+```
+
+We can also utilize the [page bundles][page-bundles] feature of Hugo to organize the image files together with the Markdown file. To achieve that, turn the `my-page.md` file into a directory `my-page` and put the content into a file named `index.md`, and put the image files inside the `my-page` directory:
+
+{{< filetree/container >}}
+  {{< filetree/folder name="content" >}}
+    {{< filetree/folder name="docs" >}}
+        {{< filetree/folder name="my-page" >}}
+            {{< filetree/file name="index.md" >}}
+            {{< filetree/file name="image.png" >}}
+        {{< /filetree/folder >}}
+    {{< /filetree/folder >}}
+  {{< /filetree/folder >}}
+{{< /filetree/container >}}
+
+```markdown {filename="content/docs/my-page/index.md"}
+![](image.png)
+```
+
+Alternatively, we can also put the image files in the `static` directory, which will make the images available for all pages:
+
+{{< filetree/container >}}
+  {{< filetree/folder name="static" >}}
+    {{< filetree/folder name="images" >}}
+        {{< filetree/file name="image.png" >}}
+    {{< /filetree/folder >}}
+  {{< /filetree/folder >}}
+  {{< filetree/folder name="content" >}}
+    {{< filetree/folder name="docs" >}}
+        {{< filetree/file name="my-page.md" >}}
+    {{< /filetree/folder >}}
+  {{< /filetree/folder >}}
+{{< /filetree/container >}}
+
+Note that the image path begins with a slash `/` and is relative to the static directory:
+
+```markdown {filename="content/docs/my-page.md"}
+![](/images/image.png)
+```

+
+| Parameter  | Description                           |
+|----------- |---------------------------------------|
+| `link`     | URL (internal or external).           |
+| `title`    | Title heading for the card.           |
+| `subtitle` | Subtitle heading (supports Markdown). |
+| `icon`     | Name of the icon.                     |
+
+## Image Card
+
+Additionally, the card supports adding image and processing through these parameters:
+
+| Parameter  | Description                                 |
+|----------- |---------------------------------------------|
+| `image`    | Specifies the image URL for the card.       |
+| `method`   | Sets Hugo's image processing method.        |
+| `options`  | Configures Hugo's image processing options. |
+
+Card supports three kinds of images:
+
+1. Remote image: the full URL in the `image` parameter.
+2. Static image: use the relative path in Hugo's `static/` directory.
+3. Processed image: use the relative path in Hugo's `assets/` directory.
+
+Hextra auto-detects if image processing is needed during build and applies the `options` parameter or default settings (Resize, 800x, Quality 80, WebP Format).
+It currently supports these `method`: `Resize`, `Fit`, `Fill` and `Crop`.
+
+For more on Hugo's built in image processing commands, methods, and options see their [Image Processing Documentation](https://gohugo.io/content-management/image-processing/).
